Abstract

The problem in this research is the low ability of students 'problem solving, the low activity of students' mathematics learning, and the low ability of the teacher in managing learning. To overcome these problems, a Novick learning model is applied. This type of research is classroom action research. Where the population of this study was all class 11 IPA-1, totaling 31 students. Data collection techniques in this study were tests and observations. The results of the study can be seen from the test of students' problem-solving abilities in cycle I and cycle II there is an increase of 23.42% and have met the completeness criteria of ≥ 80% with the category "Good". Observation of student activities in cycle I and cycle II there was an increase of 27.8% and had met the completeness criteria of ≥ 80% with the "Good" category. Teacher performance in mathematics learning in cycle I and cycle II there was an increase of 16.6% and had met the completeness criteria of ≥ 80% with the category "Good".

Abstract

Mathematical communication skills are one of the abilities that students must have to make it easier to solve problems contained in mathematics itself and in everyday life. Because if students have mastered mathematical communication skills, it will make it easier for students to take deeper learning. This study aims to analyze the difficulty of students' mathematical communication skills using the Google Classroom Application in the Algebra course. This type of research is descriptive qualitative. The subjects of this study were tree semester students who took Algebra courses in the Mathematics Education study program at Universitas Muhammadiyah Tapanuli Selatan, academic year 2020/2021 as many as 15 people. The instrument used in this study was Test and interview. The results showed that based on the test results obtained: difficulties in the ability to interpret mathematical ideas rationally in writing, difficulties in mathematical problems into mathematical models and difficulties in the ability to express mathematical ideas in the form of descriptions. Meanwhile, based on the results of the interview, namely: (1) technical difficulties, and (2) student adaptation difficulties. To overcome these difficulties, it is necessary which is a combination of Online and Offline learning or also called blended learning.

Abstract

This study aims to determine the relationship and the extent of influence between mathematical resilience and students' mathematical problem-solving abilities in basic mathematics courses. This research is motivated by the perception of students who tend to be negative towards mathematics as well as an attitude of lack of confidence and easily give up in solving the given questions. In addition, students' mathematical solving abilities are also classified as low, even though this ability is very important because it is the basis and general goal of learning mathematics. The method used in this research is quantitative descriptive method. The population in this study were all Semester I students of the Computer and Informatics Engineering study program at STKIP AL Maksum Langkat which consisted of 5 classes and took basic mathematics courses, while the research sample was taken using purposive sampling technique, which is a technique of determining and taking the specified sample. by researchers with certain considerations. The sample consisted of 35 students. The instruments in this study were test questions in the form of mathematical problem-solving abilities and non-test questions in the form of a mathematical resilience scale. Then the data is processed using hypothesis testing techniques, correlation analysis and simple regression assisted by SPSS and Microsoft Excel. The results showed that there was a positive relationship between mathematical resilience and students 'mathematical problem-solving abilities with the effect of mathematical resilience by 41.3% on students' mathematical problem-solving abilities.
